OBJECTPROPERTY (Transact-SQL)

id

Is an expression that represents the ID of the object in the current database. id is int and is assumed to be a schema-scoped object in the current database context.

property

Is an expression that represents the information to be returned for the object specified by id. property can be one of the following values.

Note
Unless noted otherwise, NULL is returned when property is not a valid property name, id is not a valid object ID, id is an unsupported object type for the specified property, or the caller does not have permission to view the object's metadata.

int

Returns NULL on error or if a caller does not have permission to view the object.

A user can only view the metadata of securables that the user owns or on which the user has been granted permission. This means that metadata-emitting, built-in functions such as OBJECTPROPERTY may return NULL if the user does not have any permission on the object. For more information, see Metadata Visibility Configuration.

The Database Engine assumes that object_id is in the current database context. A query that references an object_id in another database will return NULL or incorrect results. For example, in the following query the current database context is the master database. The Database Engine will try to return the property value for the specified object_id in that database instead of the database specified in the query. The query returns incorrect results because the view vEmployee is not in the master database.

USE master;
GO
SELECT OBJECTPROPERTY(OBJECT_ID(N'AdventureWorks2012.HumanResources.vEmployee'), 'IsView');
GO

OBJECTPROPERTY(view_id, 'IsIndexable') may consume significant computer resources because evaluation of IsIndexable property requires the parsing of view definition, normalization, and partial optimization. Although the IsIndexable property identifies tables or views that can be indexed, the actual creation of the index still might fail if certain index key requirements are not met. For more information, see CREATE INDEX (Transact-SQL).

OBJECTPROPERTY(table_id, 'TableHasActiveFulltextIndex') will return a value of 1 (true) when at least one column of a table is added for indexing. Full-text indexing becomes active for population as soon as the first column is added for indexing.

When a table is created, the QUOTED IDENTIFIER option is always stored as ON in the metadata of the table, even if the option is set to OFF when the table is created. Therefore, OBJECTPROPERTY(table_id, 'IsQuotedIdentOn') will always return a value of 1 (true).

A. Verifying that an object is a table

USE AdventureWorks2012;
GO
IF OBJECTPROPERTY (OBJECT_ID(N'Production.UnitMeasure'),'ISTABLE') = 1
   PRINT 'UnitMeasure is a table.'
ELSE IF OBJECTPROPERTY (OBJECT_ID(N'Production.UnitMeasure'),'ISTABLE') = 0
   PRINT 'UnitMeasure is not a table.'
ELSE IF OBJECTPROPERTY (OBJECT_ID(N'Production.UnitMeasure'),'ISTABLE') IS NULL
   PRINT 'ERROR: UnitMeasure is not a valid object.';
GO

B. Verifying that a scalar-valued user-defined function is deterministic

USE AdventureWorks2012;
GO
SELECT OBJECTPROPERTY(OBJECT_ID('dbo.ufnGetProductDealerPrice'), 'IsDeterministic');
GO

C. Finding the objects that belong to a specific schema

USE AdventureWorks2012;
GO
SELECT name, object_id, type_desc
FROM sys.objects 
WHERE OBJECTPROPERTY(object_id, N'SchemaId') = SCHEMA_ID(N'Production')
ORDER BY type_desc, name;
GO
